This 04-08 Acura TSX cold air intake is from Injen's premiere SP line of intakes.
Injen is probably the last true performance intake company left. If you look at an Injen intake, it immediately stands out as being thicker than other intakes. In addition, they tend to be shaped unusually. That's because they don't breeze through R&D to just bring a passable intake to market. They spend a lot of time to create the absolute perfect intake for your TSX.
The SP Cold Air line of intakes is Injen's premiere intake line. They use MR technology to create a multi-diameter intake that produces optimal power, in a cold air design that pulls colder denser air from outside the engine bay. They also pay special attention to your MAF sensor, tuning their intakes not to give too much or too little air to confuse your TSX's computer.

04 08 Acura TSX K&N Typhoon Intake Systems are perhaps the perfect cold air system for your TSX. While they still have the same great engineered designs and components that have made K&N the BIGGEST name in vehicle filtration on the planet, K&N Typhoon intake systems take it a step further by addressing the fatal flaw of most cold air intake systems.what to do in the winter?
Instructions for most cold air intakes tell you that when it comes to traversing deep puddles or other bodies of water it is best to either avoid them, or uninstall your cold air for the entire rainy system. In the event of uninstalling the cold air, what are you supposed to drive on in the meantime? K&N Typhoon Cold Air Intake Systems offer the perfect solution for your TSX: use the upper half of the intake only which is in the shape of a safer short ram intake system.
TSX K&N Typhoon Intake Systems are really two intakes in one: a cold air for the summer and dry season, and a short ram intake system for the rainy season. All you have to do is disconnect the lower portion and move your million-mile-warranty filter further up on the pipe. The idea is pure genius. if you are going to have breaks in the pipe anyway (usually to make installation easier), why not make them where your 04 08 Acura TSX can benefit the most from it?
